The 660 Series indicators are loop powered units and the low voltage drop across their input terminals allows them to be installed in almost

any 2-wire, 4-20mA loop.

Large liquid crystal displays make the process variables easily visible at a distance. Process units are configured into the display area. Instant readout of percentage or loop current is available at the push of a button.

Field mounting units are housed in a rugged aluminium IP67, NEMA 4X case. ABS and GRP options are available for highly corrosive atmospheres.
